Dishwasher Indesit DSG 5737. The machine is 3 years old, I use it only when hot water is turned off, that is, rarely. I switched on the washing mode together with the dishes for 1 h 50 m, did not perform an idle cycle after a long break, the rinse aid indicator comes on, after 10 minutes, the time indicator switches to 10 minutes and the process ended. I put it on an intensive cycle at 2h 25m. The process went fine for the first hour, but at the washing time of 1h 10m, the machine began to drain and collect water, the time sensor began to switch from 1h 10m. up to 1h 8m, then again 1h 10m. and so on ad infinitum, draining and collecting water. Long pressing the start button did not give any result, I had to select the shortest wash program for 8 minutes, it, fortunately, completed the washing process and I was able to open the car. due to the state of the dishes, the sink was, unfortunately, it was unclear whether there was heating, although the sounds were normal and the indicators (except for the rinse aid) did not signal anything. What could be the reasons?
